HENRY D. BARNES, OF NEI/V HAVEN, CONNECTICUT.
IMPROVEMENT IN FLARING METAL HOOPS.
Specification forming part of Letters Patent No. I15,0 l 5, dated November 15, 1864.
To all whom it may concern Be it known that I, HENRY D. BARNES, of New Haven, in the county of New Haven and State of Connecticut7 have i-nvented a new and useful Improvement in Flaring Metal Hoops 5 and I do hereby declare the following to be a full, clear, and exact description of the same when taken in connection with the accompanying drawings and the letters of reference marked thereon, and which said drawings constitute part of this specification, and represent, in-
Figure l, a side view of a machine for ilaring hoops upon my improved plan, and inFig. 2 a sectional view of the same.
My invention is designed to give the necessary flare to metal hoops-as for barrels, pails, &c.when it is iequired that the hoop be oi' a larger diameter upon one edge than the other. Heretofore the are has been given by rolling or hammering the hoop upon the flat sides to stretch one edge. This operation makes one edge thinner than the other, very much weakens the hoop, leaves a roughedge, often cracks orentirely destroys the metal. The object of my invention is to overcome these objections and give to the hoop the requisite curvature, preserving and nishing the edges of the metal; and it consists in passing thestrip of metal between rollers, or their equivalent in such manner that the rolls bear only upon the two edges of the metal, whereby the edges are left smooth and of their original thickness, curved with the utmost accuracy.
To more fully illustrate my invention, I will proceed to describe my manner of curving,
strips of metal in order to give them the necessary flare.
In the accompanying drawings, A is a frame supporting in proper bearings three rolls, B C D. In the face of each of the said rolls I form grooves (one or more) a a in width the thickness of the metal from which the hoop is to be formed, and of a proper depth, nearly onehalf the width of the metal. (See Fig 2.)
The said rolls are made to revolve together by means of gears E upon their shafts, power being applied to either one of the three. When revolving, insert the metal M to be curved into' its proper groove, adjusting the upper roll to give it its proper curve. The rolls revolving will draw the metal through, rolling the edges smooth, and curving it as desired, (see Fig. 2,) so that when bent into a hoop it will be properly liared for the purpose for which it is designed.
I do not claim as of my invention rolling metal for the purpose of curving it, as such is common and well-known.
I do not claim rolling hoops to reduce one edge in thickness for the purpose of giving the requisite flare; but,
Having fully set forth my invention, what I do claim as new and useful, and desire to secure by Letters Patent, is
Giving to a metal hoop the requisite flare by rolling upon its edges, substantially as and for the purpose herein set forth.
'HENRY D. BARNES.
